1. Renal Revending Project

2. Reverse vending - our journey
Revending
Deposit machines for returning drinks bottles and cans. Ensures compliantly segregated metals and plastics. Reduces the volume of items ‘less air’ which maximises storage. Rewards the users and promotes recycling. Three machines at Barts Health, collected over 5,000 items in 2 years.

3. Reverse vending - more benefits
Revending
Moves us up the waste hierarchy. Meets TEEP [Technically, Environmentally & Economically Practicable] Regulations. Reduces costs and emissions. Less portering time. Reduces recycling costs - MDR or commodity resale. Transport miles and fuel costs down, carbon footprint down.

4. Renal Dialysis plastics
What next? Got us thinking…
Renal Dialysis plastics
Barts Health has four Renal Dialysis Units at its three Acute hospitals, with a throughput of over 200 patients per day using these 6 litre HDPE bottles, six days per week. That’s 1’200 HDPE bottles per week or 62’400 a year. Each empty HDPE bottle weighs 280 grams. So, for every 10,000 of these empty HDPE bottles being thrown away, equates to 2.8 tonnes of virgin HDPE plastic being burnt as RDF [Refuse Derived Fuel].

5. Wasting time, wasting bags, wasting virgin plastics!
Lets do the maths…
Wasting time, wasting bags, wasting virgin plastics!
Lack of waste storage space, means that for every waste bag containing 9 empty bottles, has to be removed to a waste cart on each occasion. On average, that’s 22 portering movements per day just for this waste bag alone… And 22 clear domestic waste bags per day. And filling up 2½ waste carts per day. Finally, they take up huge volumes of space in our RDF compaction machines.

6. Review, make the case, influence change?
What if we could…
Review, make the case, influence change?
Could we engage with our reverse vending partners and create a machine small enough to fit into some of our Renal Dialysis Units and compact large quantities of these 6 litre HDPE bottles? Reverse vending agreed to the challenge. We would save £13,000 over 10 years from reduced use of waste bags, bag and waste cart movements [60% reduction in portering time], increase in efficiency of compactor loads by diverting this waste stream out of RDF. More savings from sending these bottles off as DMR or commodity resale. Machines would be cost neutral in 5 years. Risk free; Reverse Vending would design, make, license and maintain the machines.

7. 2 Renal Revending machines
So new machines are created
2 Renal Revending machines
Installed at two Renal Dialysis Units producing the most bottles. One at Whipps Cross University Hospital and One at Newham University Hospital Reduces the pressure on waste storage areas. Compacts HDPE bottles by 60% of their original volume. Between the two machines, they compact over 43,000 bottles per year. Each machine [and bag] holds up to 40 compacted bottles, requiring no more than two empties per day. Less portered movements; less plastic bags.

8. Collection & Recycling
The process
Collection & Recycling
When enough items are collected, HDPE is bailed
HDPE sent for reprocessing
DMR / commodity resale
Machine emptied twice per day
Items stored
